Period = 1/frequency.
Because the frequency is 261, 1/261 = the period :)

Herz is a measurement for how many cycles of the wave occur per second, which in this case is 261. the period is the time it takes to complete 1 cycle, so if 261 cycles occur per second, one cycle occurs every 1/261 seconds

A line that describes volume across the surface of an object or shape is called a ____ line.
Sergio039 [100]
A line that describes volume across the surface of an object or shape is called a cross-contour line. These are lines that would reflect the eye's movements of what you see around. These describes form and volume as compared to contour lines which describe edges only. These lines would help in understanding a three dimensional form in a form of 2D.

Find the mass if the force is 18 N and the acceleration is 2 m/s2.
Flura [38]

Answer:

<h3>The answer is 9 kg</h3>

Explanation:

To find the mass given the force and acceleration we use the formula

m =  \frac{f}{a}  \\

where

f is the force

a is the acceleration

We have

f = 18 N

a = 2 m/s²

We have

m =  \frac{18}{2}  \\

We have the final answer as

<h3>9 kg</h3>

Hope this helps you
